Matthew Poole and continuators on 1 Chronicles 7:14

14 The sons of Manasseh; Ashriel, whom she bare , (but his concubine the Aramitess bare Machir the father of Gilead .

i. e. Grandehildren, as, v. 13. For both Ashriel and Zelophehad were the Grandchildren of Machir Son of Manasseh, Numb. 26. 29, &c. and 27. 1.

To wit, his Wife, as may be thought, because his Concubine is here opposed to her. Or, whom he got; for the Hebrew Word yalad is sometimes used of Mens begetting, as, Gen. 5. 18, &c Compare Psal. 2. 7. But these and the following words may be otherwise rendred according to the Hebrew Text, whom his Concubine the Aramitess bare, who bare him (which Ellipses are very frequent in the Hebrew) for meeth, of, or by Machir: So this was a differing Ashriel from him named Numb. 26. 31. for that was Gileads Son, and this his Brother.

A Person so called, as is manifest from v. 17. & Numb. 26. 29.
